FEED-WATER CLEANER.

SEPECIFIGATIQN forming part of Letters Patent No. 320,511, dated June23, 1885.

Application filed February 25, 18:5. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANK TROWBRIDG a citizen of the United States,residing at Fond du Lac, in the county of Fond du Lac and State.

pose of cleansing the same from deposits of dirt, 820., from thefeedwater. To this end it contemplates the employment of a receptacle orvessel interposed between the feed-water heater and the boiler and meanswhereby the feed-water may be caused to flow from the heater through theinterposed vessel and its contained cleansing compound on its way to theboiler, or may be caused to flow directly from the heater to the boilerwithout passing through said vessel, at the will of the operator.

It is well known to those skilled in the art to which my inventionappertains that earth and other foreign substances held in solution inthe feed-water accumulates in the boilers into which water is passeddirectly from a reservoir, river, or pond, such deposits of foreignmatter as are indigenous to the water of a particular locality servingto damage the boiler by causing rust, frothing, &c., therein. It is alsoknown to be an almost impossible task to wholly filter the feed-water ofits impurities, which necessitates the introduction of various compoundsinto the boiler for the purpose of cutting or disintegrating thedeposits to facilitate their removal.

The invention therefore consists in the construction, arrangement, andcombination of parts whereby cleaning compounds may be intermixed withthe feed-water as it flows into a boiler, substantially as hereinafterdescribed and claimed.

The drawing represents an elevation of my device in connection with aboiler and the feed-water heater thereof.

Referring to the drawing, A designates a steam-boiler in position upon asuitable furnace, B, and provided with steam-drum a and steam feed-pipea.

G designates the feedwater heater, preferably provided with an interiorsteam-heating coil, connected by a pipe, 0, with the exhaustport of thesteam-engine. If desired, however, water in the heater may receive heatfrom any source other than that above described.

D designates the feed-pipe of the heater 0, through which water isintroduced in any desired manner to said heater.

E designates the boiler feed-pipe extending from the top of the heater Gto the mud-drum F (shown by dotted lines) of the boiler A. The feed-pipeE is provided with a valve, 0, for a purpose hereinafter explained, anda checkvalve located between said valve 6 and the heater 0. l

G designates a pipe connecting at g with the pipe E, and extendingthence to the top of and entering a vessel, H, interposed between thefeed-water heater 0 andthe boiler A. The pipe G is provided near its topwith a valve, 72, the purpose of which is hereinafter described. Thevessel H is provided at its top with a hand-hole, closed in the usualmanner.- viz., by a plate, h, (shown by dotted lines,) held in positionby a hand-screw, hfland bridge If.

I designates a pipeprojecting upward from the vessel H, and providedupon its top with a cup, '1 and at its middle with a valve, 6.

K designates a pipe connecting the vessel H with the mud-drum F of theboiler, and having a pipe, K, provided with a valve, k, the purpose ofwhich will presently appear.

L designates a discharge-pipe having one end communicating with thevessel H, near the lower end thereof, and provided with a valve, Z.

When it is desired to introduce cleansing compounds into the boiler withthe feed-water thereof, said compounds, if in liquid form or in the formof powder, are placed in the cup, the valve of which is now opened andthe compound allowed to pass to the interior of the vessel H, afterwhich the valve h of the pipe G is opened, thereby admitting waterthrough the pipes E and G to the vessel H, i

from whence, after being thoroughly mixed with the compound in saidvessel H, it is, by the opening of the valve in in the pipe K, allowedto flow through said pipe to the boiler.

\Vhen the cleansing compounds consist of the valve 6 of the pipe Eopened.

It will be understood that the pipes K and E may connect directly withthe boiler A, instead of the mud-drum F.

Modifications in details of construction above described may be madewithout departing from the spirit of or sacrificing the advantages of myinvention. I would there fore have it understood that I reserve theright to make such changes in the construction which I have shown anddescribed as an embodiment of my invention as fairly fall within thescope thereof.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In a feed-water cleaner, the combination, with the feed-water heater0, a boiler, A, supply-pipe E, having valves 6 e, vessel H, interposedbetween said boiler and heater, pipe G, connecting said pipe E with thevessel H, and pipe K, connecting the vessel H directly with the boilerA, all constructed and arranged substantially as shown and described.

2. In a feed-water cleaner, the combination of the following elements,viz: a boiler, a mud-drum, supply-pipes K, E, and G, and their valves,compound receiving-vessel having hand-hole and plate, hand-screw,bridge, and pipe I, the latter having a cup and valve, and water-heaterhaving a feed-pipe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK TROWBRIDGE.
